- Type of inhalation exposure:
- nose only
- Vehicle:
- air
- Mass median aerodynamic diameter (MMAD):
- >= 1 - <= 4 µm
- Details on inhalation exposure:
- - Experimental Design
The 4 hour acute inhalation exposure was carried out using nose-only inhalation exposure equipment supplied by CH Technologies, USA. This dynamic inhalation exposure system consists of a flow-past nose-only inhalation exposure chamber with Perspex rat exposure/restraint tubes, air compressor, flow meter, rotating brush generator (dry powder), cascade impactor, temperature and humidity probe (thermo-hygrometer), oxygen monitor, carbon dioxide monitor, and open face gravimetric filter sampler.
- Inhalation Equipment
The rats were exposed using a nose-only inhalation exposure system with a dynamic air flow rate of 727 to 728 air changes per hour, ensuring an adequate oxygen content of at least 19% and a homogeneous, evenly distributed, respirable test aerosol with a mass median aerodynamic diameter (MMAD) particle size ranged between 1-4 microns. An exposure atmosphere CO2 level was less than 1%.
- Description of Inhalation Chamber
The dynamic inhalation equipment has 2 main parts namely outer plenum and inner plenum. Inner plenum volume is 862 cm3 and outer plenum volume is 1,200 cm3 so the total volume = 2062 cm3 = 2.062 Liters. The exposure unit (outer plenum) is made of stainless steel with 12 portholes to accommodate transparent perspex rat exposure tubes. These exposure tubes are accommodated in the portholes of the inhalation chamber. The adjustable unit of the exposure tube is set in such a way that rats breathe the test item aerosol through the window panel of the exposure tube. Observations during the inhalation experiment are made through transparent perspex rat exposure tubes. The outlet unit connected to a suction pump. The outgoing air from the chamber passes through an impinger containing 1.0% sodium hydroxide solutions and moisture traps.
- Description of Dust Generator System
The dust generator system is manufactured by PALAS GmbH and supplied by CH Technologies (USA), Inc. The dust generator system is a long assembly of tubing having several tube fittings attached. The feed system consists of a feed stock reservoir, generating system consists of a brush housing with integrated brush, spacer holder, up/down schalter, inlet of air for diserpsion, connection of compressed air with reducer, switch for manual or external controls (air, brush speed, schalter speed). - Analytical verification of test atmosphere concentrations:
- yes
- Duration of exposure:
- 4 h
- Concentrations:
- The nominal concentration of aerosolized substance was calculated to be 10.277, 6.646 and 3.446 mg/L air for group I, II and III, respectively, based on the mass of test item which used during exposure and the total chamber air flow during exposure.
- No. of animals per sex per dose:
- In the main test, 5 males and 5 females were tested per dose.
- Control animals:
- no
- Details on study design:
- OBSERVATIONS
- Toxic Signs
All rats were observed for any signs of toxicity and mortality hourly, during the 4 h exposure period and at 1 and 2 h after the exposure on the day of exposure. Subsequently, surviving rats were observed twice a day for morbidity and mortality for a period of 14 days following exposure. Clinical signs were recorded once a day.
- Body Weight
Body weights were recorded prior to exposure on day 0 and on days 1, 3, 7, and 14 and at death.
- Necropsy
At the end of the study, all survived rats were sacrificed by intraperitoneal administration of thiopentone sodium and subjected to gross pathological examination. All found dead rats were also subjected to gross pathological examination. This consisted of an external examination and the opening of the nasal passage, abdominal, and thoracic cavities. The appearance of any macroscopic abnormality was recorded. - Statistics:
- As this study was conducted as a full study at three different breathing zone concentrations, the acute inhalation median lethal concentration (LC50) of the test item was calculated from the observed mortality data by the Probit analysis (Finney, 1971) method.

- Necropsy (Macroscopic Findings):
- External: External examination of the found dead and terminally sacrificed rats did not reveal any abnormality of pathological significance.
- Internal: Visceral examination of the found dead rats revealed liver: reddish discolouration (Rat Nº 1, 3, 4 and 9) and lungs: multiple whitish foci (Rat Nº 13, 17, 19 and 24) whereas other found dead and terminally sacrificed rats did not reveal any lesion of pathological significance. Lesions observed in the found dead rats could be correlated with the test item used in the present study. - Other findings:
- External examination of the found dead and terminally sacrificed rats did not reveal any abnormality of pathological significance. Visceral examination of the found dead rats revealed liver: reddish discolouration (Rat N º 1, 3, 4 and 9) and lungs: multiple whitish foci (Rat N º 13, 17, 19 and 24) whereas other found dead and terminally sacrificed rats did not reveal any lesion of pathological significance.
Interpretation of results :
The calculated acute inhalation median lethal concentration (LC50) value of the test item for combined sex was 2.091 mg/L air with 95% lower fiducial limit of 1.717 mg/L air and upper fiducial limit of 2.548 mg/L air. The regression equation is y = -15.264 + 6.103 x.
The calculated acute inhalation median lethal concentration (LC50) value of the test item for male rats was 2.314 mg/L air with 95% lower fiducial limit of 1.524 mg/L air and upper fiducial limit of 3.515 mg/L air. The regression equation is y = -8.001 + 3.864 x.
